Imagine a world full of only millennials, but your age is based on what year you were born

Our world will start on January 1st 1997.

If you were born in 1996, you are a newborn baby. Each year before that add 7 years.

For example, if you are born in December 1990, it would be 0+7+7+7+7+7+7 = 42. So you will be 42 years old starting in this world on January 1st 1997. Add 3.5 years if you are born before July.

Where do you fall? What do you think you would be doing?

Since I'm February 1995, I would be 10.5 years old with our world starting on January 1st 1997.

I think I would be spending a lot of my time on my PlayStation playing Crash Bandicoot.
